Application ined December 6, 192e.'` serial Nb; 152,953;

This invention relates to improvements in valve lifters embodying amongother characteristics adjusting means for adapting a lifter upon thevarious forms of valves in different malte of motors.

Another object of the invention comprehends a lifting member carried bythe operating lever adapted for engagement with a spring cup and toreceive a portion of the valve stein and adapted for upward travelingmovement upon similar ymovement imparted to the operating levei'.

A further object contemplates a locking dog carried by the operatinglever adapted for reception -within cut out portions in the liftingmember to lock the device in a given position while extracting a valvepin.

More specifically stated a linger engaging element is carried by theimparting dog to permit releasing` of the latter.

With the above and other objects "iii view the invention furtherconsists of the following novel features and details of construction tobe hereinafter more fully described and pointed out in the appendedclaims.

In the drawings:

Figure 1 is an elevation of the invention partly in section while inuse, and

Figui-e 2 is a perspective view of the invention.

Referring to the drawing in detail wherein like characters of referencedenote corresponding parts, the reference character 10 indicates aportion of the motor vehicle, 11 the valve guide sleeve, 12 a valve stemadapted for reciprocatory movement therein and 13 and 141 the valvespring and cuptherefor. The conventional form of Valve pin is indicated15. All of the above is of the usual construction incident to that ofvalve mechanisms which form no part of the applica tion forletters-patent but which are merely mentioned for purposes ofillustration in bringing forward the novel advantagesoi the aboveentitled invention,

In carrying out myv invention I provide an operating lever 1G whichincludes long and short elongated slots 17 and 18 respectively,vdisposed axially of the longitudinal center of the operating lever. Apin 19 carried adjacent one end of the operating lever 16 is adapted forengagement with the cylinder block of the engine. The forward end of theoperating lever is provided with a flattened portion 19 taperedlongitudinally thereof y and conforming to,` Athe i level of j thev.valve heads to lie flush therewith. An L-shaped lifting member 2O hasthe upper end and verticalleg thereof extending upwardly through thelong elongated slot 17. A pin 21 carried by the operating lever 16within. the elongated slot 17 is adapted for selective re ception withinany one of a plurality of out out portions 22 provided in the forwardside edge of the lifting member 20. The offset or transverse leg of thelifting member 2O provides a fork portion 23 adapted to receive thevalve stem 12 and to seal the valve cup 14 upon the upper side thereof.Said fork portion is disposed in direct alignment with the pin 19carried upon the adj acent forward end of the operating lever 16 whensaid pin is called into use. A locking dog 2li pivotally mounted withinthe slotted portion 18 terminates to provide a forwardly projectingreduced extension 25 which is adapted to be positioned within any one ofa plurality of cut out portions 26V disposed at spaced intervals uponthe rear side edge of the L-sliaped lifting member 2() to lock thedevice in position; substantially as illustrated in Figure 1 of thedrawing to permit the removal of the valve pin 15.

hook 27 vcarried by the locking dog 24 serves as a finger engagingportion to release the locking dog 24 from the lifting member 2O whenthe operating lever 16 is pushed upwardly.

The invention is susceptible of various changes in its form, proportionsand minor details of construction, and the right is herein reserved tomake such changes as properly fall within the scope of the appendedclaims. I-Iaving thus described the invention, what I claim as new is: n

1. A valve lifter, comprising an operating lever, adapted to be engagedupon the top of the valve, an L-shaped lifting member, adapted forengagement `with the valve `spring seat, one edge of said lifter memberbeing provided with a series of notches and said operating lever havinga transverse element selectively engageable with said notches, the otheredge of said L-sliaped lifting member being provided with a series ofnotches, and a retaining dog, pivotally suspended from the operatinglever and detachably engageable with a selective one of the second namedseries of notches.

2.
